Earlier this week, Texas Motor Speedway announced plans to fit the world's largest HD TV on the backstretch of the track. TMS are working with Panasonic to make a screen that's 218 feet long and 94.6 feet wide, or in other words, nearly 12 stories high and almost 21,000 square feet. All being well, it should be ready for the NASCAR weekend in April. I've saved the best bit 'til last - they're calling it "Big Hoss TV" .
